Network Edition and msi customizing?

Hello we have the Network Edition running in our Company.
Now i want to customize the outlookConnector installer.
I have copied the js file to C:/ and as well the .msi file:ZimbraOlkConnector-4.5.5_GA_831_4.5.230
Now i start cmd and typed the following:
cscript ZmCustomizeMSI.js ZimbraOlkConnector.msi servername 443 1 //nologo

after that it gives me the error: invalid parameter 443

What is wrong?
And by the way could i give the installer a company-logo? If yes how?

PS: got the newest Network Edition 100Users.
Would be grat to get some quick response on this issue...time is running.
Thanks a million
